Effects of low-level red light therapy on myopic minors' eye health

Fundus Effects of Repeated Low-Level Red-Light Therapy in Chinese Myopic Minors: A Randomized Controlled Clinical Trial

Not applicable Interventional Zhongshan Ophthalmic Center, Sun Yat-sen University · NCT06034912

This study is testing if low-level red light therapy can help improve eye health in kids aged 7 to 17 who are nearsighted, compared to those using regular glasses.

What this trial studies

This clinical trial investigates the short-term effects of repeated low-intensity red light therapy on the fundus of the eyes in minors aged 7 to 17 with myopia. It employs a randomized controlled design with participants divided into an experimental group receiving the therapy and a control group using standard corrective glasses. Various assessments, including optical coherence tomography and microperimetry, will be used to evaluate retinal functionality and potential damage. The study aims to provide insights into the safety and efficacy of this novel treatment approach for myopia management.

Who should consider this trial

Good fit: Ideal candidates are minors aged 7 to 17 with specific refractive errors and good visual acuity.

Not a fit: Patients with significant eye diseases or systemic conditions that affect vision will not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could offer a new non-invasive treatment option to slow the progression of myopia in children.

How similar studies have performed: While the approach of using low-level red light therapy is relatively novel, similar studies have shown promising results in other contexts.
